Bye, Bye AR2665 and AR2666

AR2665 and AR2666 are captured right on the edge of the solar disk in this image.


Both areas are considerably foreshortened as they approach the limb. Many spots show evidence that they are actually lower than the surrounding photosphere (they appear as depressions), but this does not seem to the be the case with AR2665. When these areas disappear, the sun will return to being featureless again.
